    • Disclosed is a magnetoelectric (ME) composite including both a piezoelectric material and a magnetostrictive material, wherein a piezoelectric single crystal material having high piezoelectric properties is used as the piezoelectric material, and a metal magnetostrictive material having high magnetostrictive properties is used as the magnetostrictive material, thus achieving an ME composite having a layered structure via adhesion. When the ME layered composite is manufactured such that a crystal orientation of the piezoelectric single crystal material is set to a thickness direction, high ME voltage coefficient, which is at least doubled, compared to a conventional crystal orientation, can be obtained, and such an effect is further maximized in the resonance of the composite.
    • 公开了一种包括压电材料和磁致伸缩材料的磁电(ME)复合材料,其中使用具有高压电性能的压电单晶材料作为压电材料,并且使用具有高磁致伸缩性能的金属磁致伸缩材料作为磁致伸缩材料 ,从而通过粘合获得具有层状结构的ME复合材料。 当制造ME层压复合体使压电单晶材料的<011>晶体取向设定为厚度方向时,与常规<001>晶体取向相比,至少加倍的高ME电压系数可以 并且这种效果在复合材料的共振中进一步最大化。
